ABSTRACT:
The present invention relates to methods and compositions for encapsulating biologically active agents in starch-based adherent granules. Simple and economic methods have been developed to prepare said adherent granules. Compositions and characteristics of the granules are disclosed, including their capability for sustained release of pest control agents. These methods and compositions are useful in controlling insects and other species of pests having chewing mouth parts and amylase digestive enzymes.
